Collins S-Line Mostly Returns

A load of Collins S-Line gear

After MUCH work and TLC by Chuck W9KR, the majority of both of my Collins S-Line stations was ready to pick up.

The 32s1 transmitter is only major piece left behind for final work, as it hasn’t been behaving as expected on each band.

On a temporary basis the RE (Round Emblem) late production transceiver – KWM-2/A with 321B5 Second VFO – and station components (30L1 Amp, 516F2 Power Supply and so on..) will be set up where my Flex-6600M runs. This will let me work the rig lunch hours and after work, as I would like to let the station run for a bit before hauling it out to Washington Island.

I’ll do the same with the 32s1/75s1/30L1/312B4/516F2 WE (Winged Emblem) station when the transmitter is done.

The work Chuck W9KR did is monumental. Recapped, Upgraded, New tubes as required, new parts as required, decades of dust & grime removed, New 572b tubes, in certain cases mouse infestations sign removed, tech bulletin upgrades, CCA upgrades, and a few Chuck W9KR upgrades – especially in improving the reliability of the 516F2 power supplies.

The gear arguably should work better than when new, should be reliable and should have all that great Collins sound.

Quietly I cannot say enough with the detective work and bench work of Chuck W9KR.  I realize that I have so much to learn just in order to fully understand all the goodness he baked into these radios.

Lots of Collins fun ahead for me working the airwaves with refreshed vintage gear!
